To examine metabolic effects of sake cake ingestion, plasma and tissues were analyzed in senescence-accelerated mice prone 8 (SAMP8) fed a sake cake diet. As a result, branched-chain amino acids (BCAA) were found to be significantly higher in the plasma, gastrocnemius muscles and brains of the sake cake group than in the control group. Mice in the sake cake group showed stronger grip strength than the control group. High levels of circulating BCAA have been reported to be associated with pathological states, such as metabolic diseases, but the parameters of glucose and lipid metabolism were not affected between the two groups. Otherwise, pyridoxal was significantly higher and nicotinamide as well as 1-methylnicotinamide showed a tendency to be higher in the plasma of the sake cake group than in the control group. These findings indicate that intake of sake cake increases the levels of BCAA, vitamin B₆, and vitamin B₃. Abbreviation: CE-TOFMS: capillary electrophoresis time-of-flight mass spectrometry
